Pettit Engines

In the past 25 years Pettit Built Rotary Engines have earned a worldwide reputation for unsurpassed quality, top
performance and outstanding reliability. Our history of racing victories and Championships in both endurance and
sprint racing are a result of our passion for improving rotary engines and paying close attention to small details.
From endurance races like the Rolex 24 & 12 hours of Sebring to our recent Victories in time attack sprints, 06/12 we
have learned the importance of every detail, one missed can make the difference between winning or being a loser. It
is easy to make a rotary fast, but our expertise is proven to make rotary engines last.
Our reputation for providing top performance and unmatched longevity was earned with each of over 1500 Pettit Built
engines delivered to clients around the globe. A reputation that is strengthened with every build and by continuing to
improve process and quality delivering the best products available regardless of cost. Now included in every Pettit Built
Engine is our latest proven technology, “Flex-armor apex seal fortification” an electro-chemical process that
strengthens 2 piece style apex seals adding strength overall and to the common point where nearly every apex seal
failure originates.

Top Quality:
So what makes Pettit engines the best and how is that done for over 1000 engines. It all starts with the careful inspection of all the selected components that make up every Pettit Built Engine, even the new parts are carefully inspected, measured and approved for each and every engine, then all modifications, porting, machining blueprinting and finishing to all critical surfaces are completed, next the parts receive a hi temperature detergent bath and hi pressure rinse by a 10hp cleaning machine. Then on to pre assembly and more inspections, to pass the pre assembly inspections, a critical surface finish of 12-18 micron is required. To consistently achieve these high Standards, Pettit developed several proprietary methods for machine and hand finishing of these critical surfaces, just one more reason Pettit Built Engines are considered by many to be the best. Next oil galleys and internal passages are inspected and a final cleaning is performed. Last stop is the engine room, each part gets another inspection and all critical openings are
sealed with caps & plugs, then during the final assembly process yet another inspection is performed for a total of 8 quality control inspections.

On top of paying close attention to every detail we also use only genuine Mazda Parts, then every engine is
personally assembled by Cam Worth, that’s right for over 20 years he personally assembled every engine ever sold by
Pettit Racing as well as countless engines for numerous race teams, all the R&D and race engines for Pettit projects
and many special engines for magazines, project cars, boats and marine use, prototype diesel and one rotor engines,
the Diasio Car Company’s 13b Renesis powered sports racers, 13b & 20b GT Car & Time Attack Car engines and
AXIO 1 rotor go kart engines.Engine Performance:
Our standard street port improves efficiency and flow with out major changes in port timing, benefits are better fuel
economy as well as more power delivered through all rpm ranges and boost levels. Our standard street ported engine
properly tuned and maintaining a charge temperature <125F @ 16-20 psi/boost with a 1:1 -1.25:1backpressure ratio is
capable of producing 200 hp / rotor. On a two-rotor engine this is 400 hp, sure these engines will make more power but
then other factors like material strength and management errors become more critical and these variables can lead to
unexpected failures.

Engine Longevity:
Engine Life is totally dependent on proper care. The best longevity is achieved by following our simple guidewww.pettitracing.com, basically never over heat the engine, easy warm ups and cool downs (no boost) keep clean oil
(no fuel smell) and to maximize performance and longevity always add Protek-R fuel lube and use good quality fuel.
100’s of our engines are still performing beyond expectation and many, for 15 years & counting.Monster Ports:
Extra large and monster ports (common with older naturally aspirated and drag race engines) can compromise
reliability. Since the seals, both apex and side pass over larger openings there is more flex resulting in accelerated
seal wear as well as greater possibility for catastrophic failures. All this should be especially evident when most
conversations about turbo rotary engines still mention seal failures.

Build Your Engine:
Due to a shortage of engine core parts the best and most cost effective method for obtaining a Pettit Built Engine is
to ship us your old engine, once here we disassemble it, perform wear pattern / failure analysis inspections and call
or email you with our findings and the exact cost to build the engine you desire. The old parts tell a story and reveal
the causes of problems and / or failure that once corrected can help prevent a future recurrence. We also offer
customers to participate in disassembly & inspection of their engine for a first look, most are surprised with the
results and glad to have had a first look, fun and popular.

Pricing:
Pettit Built 13b ….$3695 plus major parts deemed N/G, final cost depends on the condition of your engine or core,
we regularly update and refresh engines for race teams and customers world wide, engines with minimal wear and
well in spec cost between $1900 and $2500. About half the failed engines we build will need a new rotor housing adding $855 for a total of $4295. FYI.. Engine parts from Mazda have nearly doubled in price since 2002, then the cost for a new rotor housing was aprox $500 now they list for $970. April / 2012

Pettit Built OTS (off the shelf) Engines:
If you have no core, we can get a Pettit Built OTS Engine right to your door. All Pettit engines use the latest apex seal
technology from Mazda have advanced critical surface treatments, blueprinted, street ported, and hand built exceeding industry standards, tested, and skin sealed. Proven to provide performance and longevity beyond expectation!! 13b OTS $4995 plus core deposit $1000 refunded after usable core return
